Electrophoretic display (EPD) has been a prevailing paper‐like display technology for years, owing to its advantages of flexibility, low‐power consumption, and good sunlight readability. However, it is regrettable that the black/white EPD still dominates the majority of the market while a commercially sold full‐color EPD is still unavailable. In this paper, we proposed a facile yet feasible method to fabricate a color EPD by a tape‐assisted transfer method, which is the first demonstration using transfer method to achieve color micro‐encapsulated EPD.
Tb−Co alloy nanoparticle aggregates were successfully prepared by potentiostatic electrodeposition in solution of 0.5 M Tb(NO3)3 + 0.5 M CoCl2 + 0.1 M citric acid + 0.1 M LiClO4 + DMF. Cyclic voltammetry was used to investigate the electrochemical behaviors of Co2+ and Tb3+ in solution of 0.01 M LiClO4 + DMF, and the results showed that Co2+ could induce the electroreduction of Tb3+. The morphologies of Tb−Co alloy nanoparticle aggregates can be controlled by changing electrodeposition potential. The effects of the electrodeposition parameters on the compositions and morphologies of Tb−Co alloy nanoparticle aggregates were investigated in this paper. Compared with the bulk materials, the hysteresis loops of the obtained deposits showed the enhanced coercivity (H
c) and saturation magnetization (M
s) at 300 and 5 K, respectively. In addition, the magnetic properties of Tb−Co alloys can be modulated by changing deposition potential.
Cyclic voltammetry was used to investigate the electrochemical behaviors of Fe(II) and Ce(III) in
3.00 mol/L urea−dimethylsulfoxide (DMSO). The electrode processes of Fe(II) and Ce(III) reducing on
Pt electrodes were irreversible steps. Experimental results showed that Fe(II) in 3.00 mol/L urea−DMSO
could induce the electrodeposition of Ce(III). The Ce−Fe intermetallic compounds with foam structures
were successfully obtained by potentiostatic electrodeposition in the 0.01 mol/L Ce(CH3SO3)3−0.01 mol/L
FeCl2−3.00 mol/L urea−DMSO system. The concentrations of the salts and hydrogen ions have much
effect on the pore number and wall structure of the foam. The effect of the potential of electrodeposition,
Fe2+ concentration, and the ratio of the concentrations of Ce3+ to Fe2+ in the deposition solution on the
contents of Ce in Ce−Fe intermetallic compounds were investigated in our paper. The electrodeposited
Ce−Fe intermetallic compounds were amorphous as proved by X-ray diffraction analysis (XRD).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
